Full Storage Nodes

Full Storage Nodes play a vital role in upholding the integrity of the network’s data. They are responsible for storing all data faithfully and sending them to Light Nodes.

To prove that they have accurately stored all data, they must return any data requested by the light nodes. Since full nodes cannot anticipate which data the light nodes will request, it becomes probabilistically infeasible for full nodes not to store all the data.

Furthermore, when a new honest full node joins the network, assuming Nubit has entered the worst-case scenario where only one node in the network is honestly providing data, with the Checkpoints on Bitcoin, the new node can verify which one is the honest node and obtain all the real data from it.
